Improved pipeline support (and fixed positional usage).
Added custom object creation and incremental output (better performance and cleaner code).
For local host, use local path.
Added error messages for error conditions.

Opět tip z powertips
Někde v hloubi blogu je myslim už group a totožne co je na powertips jenom misto
Get-Process | Group-Object -property Company je tam seskupovaní služeb.
Ukazka z powertips ukazuje vlastni seskupení podle tří kataegorii – rozdilná velikost,jak si je kdo nazve ve scriptu nebo kolik si takových kriteríí uděla a jaká velikost bude patřit k čemu je věc jenom toho co hledám a seskupuji.
PS> $criteria = {
if ($_.Length -lt 1KB) {
'tiny'
} elseif ($_.length -lt 1MB) {
'average'
} else {
'huge' }
}
PS> dir $env:windir | Group-Object -Property $criteria
Výsledek
Tvorba hash table se samozřejmě neomezuje na velikost nebo seskupovaní procesů,nakombinovat jde spousta věcí.
Další tip který vyšel na powertips
GET-WMIOBJECT WIN32_NETWORKADAPTER | foreach { $_.Disable() }
Vypne všechny sitove adaptersy - Physical, Logical, všechny a GET-WMIOBJECT WIN32_NETWORKADAPTER | foreach { $_.Enable() }
všechny povolí
Filtr na fyzicke neboli where { $_.PhysicalAdapter –eq $TRUE} a přikaz níže zakáže pouze fyzicke adaptery
GET-WMIOBJECT WIN32_NETWORKADAPTER | where { $_.PhysicalAdapter –eq $TRUE} | foreach { $_.Disable() }
Co se týče filtrace tak fantazii se meze nekladou…
Nove procesy v danem časovem oddobí
Get-Process | Where-Object { try { (New-Timespan $_.StartTime).TotalMinutes -le 5} catch { $false } }
V jednom postu byl zminěn koncept integrace powershellu a HTML5,našel jsem tam mimo jine toto
iex (New-Object Net.WebClient).DownloadString("http://bit.ly/e0Mw9w")
vložte do powershellu a budete překvapeni stejně jako já.
Dnes jsem při upravování výstupu pro netstat v powershellu narazil v jine souvislosti na zajimavý ps1 script pro nmap.
http://blogs.sans.org/windows-security/2009/06/11/powershell-script-to-parse-nmap-xml-output/
Jeden z možných vystupů ktere exportuje potom vypadá takto
Start-demo mimochodem podporuje vylepšenou automatizaci – autoexecute mode a autospeed parametr a mnoho mnoho dalšího.Je to předělavka původního Jeffrey Snover's original Start-Demo script od Joel "Jaykul" Bennetta.
Jak pracuje start demo a jak si tam vkladat svoje sekvence je popsáno jak na strankach poshcode kde je upravené start-demo ke stažení tak někde,bůhvíkde o hodně přispěvků zpět na tomto blogu.
Na konci videa je ještě ukazka prace s profilem powershellu– jeho uprava ,vlastní alias,vložení funkce,volání funkce.
Slibovaný script pro práci s historií,význam má alespon pro mne je to tak ,pokud je v profilu.Autora a popis si vyhledejte – bude bud na pashcode nebo technet scriptcentru,změnil jsem nazev funkce a maxcount,takže kdo chce původní hodnoty může se po něm mrknout,vzhledem k tomu že ho mam v profilu původní popis scriptu už nemám.Nicmeně vychazet by se mělo z http://www.nivot.org/2009/08/15/PowerShell20PersistingCommandHistory.aspx

Zaloha vystupů z eventlogu,přidejte si připadně export kam je libo,jiným způsobem
Smazaní eventlogu – daný přiklad likviduje prostě vše,obrazek je pastnutý ale ze stroje který je prakticky co se týče zaznamů teměř netčený nějakýma vstupama jediný zaznam tam byl jak vidíte pravě o předchozím mazaní – ID 1102.
Clear je tady celeho listu,můžete si nastavit pochopitelně jenom výběrové.
get-eventlog security | export-clixml -path Seclog.xml
Import-clixml Seclog.xml
get-eventlog -list |%{$_.clear()}

Nahodou jsem viděl scripty na otevření www pomocí powershellu a všude se uvadělo že je nejjednodušší otevirat v IE.
Shay Levy http://blogs.microsoft.co.il/blogs/scriptfanatic/archive/tags/PowerShell/default.aspx ale uvádí mnohe elegantnější možnost a sice (New-Object -com Shell.Application).Open("http://www.microsoft.com")
